Some answered. I have also wondered if the ancestry email system works properly. Sometimes I receive notices that someone has responded to my messages, and sometimes I don't. Since I check my inbox at ancestry nearly every day, it doesn't matter. But if someone does not ever check their inbox at ancestry, then they would never see the invitation. I am probably OCDC, but I like to collect everyone with the surname Phillips for our project.

Did any answer your invitations? I wonder if the brokered email service
works. I sent invitations to three people that were not in our project, but
got no answer. I was able to trace their lineages, and found we didn't need
them.
